, To all whom, it may concern..-

Be it known that we, WARREN C. EVANS, residing at Exeter, in the countyof Rockingham, State of New Hampshire, and EUGENE H. TAYLOR, residing atLynn, county of EsseX, State of Massachusetts, citizens of the UnitedStates, have invented a certain new and useful Improvement inBottom-Finishing Machines for Shoes, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention consists in a machine for buffing or otherwise finishingthe bottoms of the soles, shanks, andheels of boots and shoesautomatically.

In a machine embodying the invention a shoe fitted to a form mountedupon a Workcarrier is presented by the advancing movement of the latterto a series of buffing-surfaces. The machine is provided with one or Imore of such surfaces to act upon the bottom surface of the top lift.

of the sole and shank of the said shoe and with one or more .to act uponthe wear-surface of the top lift of the heel thereof. Preferably it isequipped with a plurality of buffing-surfaces, as two, to act one afterthe other upon the sole and shank, such surfaces being of differentdegrees of fineness in order that one thereof may perform the roughpreliminary bufiing and the other thereof the finishing, and aplurality, as two, of heelbufling surfaces, also differing in fineness,to act one after the other upon the said' wear- Means is rovided wherebyafter the rear portion of t e shank has been presented to abuffing-surface for the sole and shank and acted upon thereby a relativeshift is produced by which such buffto clear each other to enable theheel to pass the buffing-surface in the continuing, movement of thework-carrier. This relative shift for pu'r oses of clearance is causedto occur for eac of the buffing-surfaces for the sole and shank. Inbufiing the shank the corresponding buffing-surfaces are caused to actthereon in close proximity to the breast of the heel. In order thatwhile the relative shift is taking place the continued advancing tworotary wor ing-surface and the heel of the shoe are caused 1 chine.

by which, concurrently with the relative shift, the advancing movementof the shoe is interrupted by a dwell or suspension affording time forthe heel and buffingsur-- face to clear each other. With the heel'-buffing surfaces are combined a 'gage which acts to measure the heightof the heel that is to be operated upon by the said surfaces and devicesoperating under the control of the said gage to set the said surfaces tosuit the height of the heel before the heel ar'- rives at such surfaces.Devices are provided by means of which as the heel passes a heel buffingsurface and the wear-surface of the top lift is acted upon by the lattera gradual shift of the said bufiing-surface and wearsurface relative toeach other-is caused to take place in a manner to suit the outwardinclination of the plane of the wear-surface of the heel. Thereby each.heel-bufling surface is caused to conform to the said inclination of thesaid wear-surface, and excessive action 11 on the rear portion of thewear sur face an resulting in ury to-the-heel are'prevented.

An embodiment of the invention is illustrated in the accompanyingdrawings. The

machine shown is essentially a double or twin machine, it being providedin practice with -carriers, that are located side by side at the frontof the machine, and

with a corresponding duplication of the buffs ing-surfacesand otherparts which act in con junction with the two work-carriers. The maindriving mechanism of themachine,

however, is not duplicated. In order to avoid encumbering the drawings,we have in the main avoided the representation of merely duplicatedparts.

In' the drawings, Figure 1- shows inend el'evation the right-hand end ofthe saidma- Fig. 1, Sheet 1, is a detail'view of the clutch devices forone of the work-carriers. Fig. 2, Sheet 2, is a view showing inrfront'elevation, on an enlargedscale, a portion of themachine at theright-hand end thereof. Fig. 3, Sheet 3, is a view in section on thedotted line 3 3 of Fig. 2 looking in the direction indi cated by thearrows at the ends of such line, showing, on a larger scale than=Figs-.1 and-2, a work-carrier and the'means for producing the inward andrearward movement of the shoe to obviate accidental engagement of 20tion with a work-carrier.

Figs. 23 and 24, Sheet 7, are respectively aside elevation and an edge view of the adjustable cam by which theposition of the bufling-band frames is controlled and by which suchframes are op- 5 5 erated to withdraw the bufiing-bands froin the pathof movement of the heel of a shoe supported upon the work-carrier. Figs.25 to 30, Sheet 7, are views showing the details of the adjustable camthat is represented in Figs. 23 and 24. Fig. 31, Sheet 8,. is a view onthe same scale as Figs. 1 and 17 of the machine in section 'ona verticalplane in the right-hand half of the machine extending from front torearandshowing chiefly the parts which are involved in buffing the heelbest in Fig. 17 of Sheet 5 and Fig. 33 of Sheet 10,) supported by thesaid base or stand, the

upright intermediate frame-piece a Fig. 2

and Figs. 32 and 33, Sheets 9 and 10, which also is supported by thesaid base and girths, one of which is shown at a, Fig. 2 and Figs. 17and 31 of Sheets 5 and 8. The power or driving shaft is shown at b, Fig.1 and Figs. 17, 31 32, and 33, it being mounted in sultable bearings atthe rear in the machine in the upright portions of the framing. In Fig.33 the said shaft is shown furnished with fast and loose band-pulleys bb for the reception of a driving-belt, (not shown,) a suitablebeltshipper (also not shown) being provided in practice for throwing thepower on and off, or other approved driving and power-shipping devicesmay be employed, as preferred.

A shoe 0, that is to be operated upon, is 5 placed u on a form (1, Fig.3 of Sheet 3, thecombine form and shoe being applied to a jack e, Figs.2, 3, and 4, forming part of a work-carrier which is mounted upon awork- 1 carrier shaft b. As thus applied, the bottom of the shoe isturned outward, and thus ex posed to the action of the buffing-surfaceswhich are arranged'around the work-carrier. By rotary movementcommunicated to the work-carrier the shoe 0 is presented to one afterthe other of the successive buffing-surfaces, so as to be operated uponby the latter in turn. The buffing-surfaces comprise a coarsebuffing-band 11, (shown in place in the machine in Figs. 1, 2, &c;, andalso shown in no the detail views, Figs. 18 to 21, Sheet 6,) a finebuffing-band 1', corresponding in general character with buffing-band i,these two operating upon the sole or, preferably, sole and shank of theshoe as it is'presented to them in turn, and the coarse bufling roll orcylinder 7c and fine bufling roll or cylinder Z, (shown in Figs. 1, 31,and 32,) these rolls or cylinders operating upon the wear-surface of thetop lift of theheel of the shoe as the said I 2c wear-surface ispresented to them in turn.

For the support of a form and the shoe which has been applied theretothe jack e is furnished with a pin 6 to enter a hole in the top of therear part of the form, and with a 12 rest 6 against whichlies the forepart of the i said shoe. In order to enable the fore part'of the formand shoe to be pressed toward the said rest and the pin 6 to be crampedwithin the hole in the rear part of the form, so as to 1 0 prevent thelatter from slipping off the pin, the pin is connected with the rearportion of the jack by means of a pivot e, and a projecting tail portionof the pin is pressed against by a plunger or pin 6 occupying a socketin said rear portion of the jack and pressed outwardly by an expandingspiral spring 6 that is compressed between the plunger and the inner endof the socket. To suit different lengths of shoes, the fore-part rest .eis mounted upon a dovetailed way upon an inclined portion e of the frontportion of the jack and is adjustable along such inclined portion, aclamping-screw e serving to secure it in its position of adjustment. Thestem of the said clamping-screw passes through a slot e in the portion einto a threaded hole that is tap ed in the base of the rest 6 the headof t e clam ing-screw taking a bearing against the un er side of theportion a. i

Referring more particularly to the workcarriers and to the featuresthereof, which are represented in Figs. 2 to 10, Sheets 2, 3, and

4, each work-carrier is provided with a plurality of jacks. The drawingsshow two jacks to eachwork-carrier, which are located diametricallyoppositeeach other. By the employment of a work-carrier having two ormore jacks the output of the machine is increased, inasmuch as two ormore shoes may be operated upon at the same time. The body portion 9 ofeach work-carrier extends in o posite directions radially from the hubor s eeve thereof, which fits upon the workcarrier shaft 7t. Each of theoutwardly-extending portions of the work-carrier body has appliedthereto a jack-support For the pur oses of the relative shift by whichthe heel and the respective buffingsurfaces for the sole and shank areenabled to clear each other each jack-support is movably mounted uponthe said body ortion. To this end each j ack-support is ma e in the formof an arm and is hung to the corresponding portion of the body portionby means of a pivot-pin or j ournal f, Figs. 3, 5, and 7, with which thearm is furnished, and a bearing gf, with which the said body portion isformed and into which the said pivot-pin or journal is fitted. Thepivot-pins or journals of-the arms ff of the two jacks pertaining to awork-carrier are located at opposite sides of the axis of rotation ofthe work-carrier. The free extremity of each arm f and the jack which isattached to the said arm are movable toward and from the said axis. Therelative shift aforesaid is effected by movement of the arm and jackinward from the outer or normal position thereof, occurring after therear end of the shank of the shoe has been properly acted upon by agiven buffing-band and cooperating in t present instance with outwardmovement, which at the same time is communicated to the buffing-bandframe carrying the said buffingband. As hereinbefore indicated, therelative shift of the shoe and the said buffingband with respect to eachother in a radial direction enables the heel to pass the buffingband inthe further rotation of the work-carrier. The clearance might be securedby radial movement of either the jack or the buffing-band frame alone;but by causing the two to move simultaneously in opposite directions aneasy and quick separation is advantageously secured with less range ofmovement of individual parts, less speed and an'easier action, and lesswear and tear than would be the case if the clearance should be providedfor by movement of one of the parts only. a

The dwell or suspension in the advancing movement of the shoe, by whichthe breast of the heel is prevented from being carried against thebuffing-surface while the relative shift is taking place, is providedfor by locating the point of pivotal sup ort of the armf in the lead ofthe jack in order that when the arm swings inwardly from the outerornormal working position the movement of the jack and the shoe thereonshall take place along a rearwardly-extending curved pat-h. Movementinward along tliesaid path, carrying the jack and shoe slightly towardthe rear, offsets the effect of the continued forward rotation of thework-carrier and produces the desired brief suspension ordwell in theadvance of the jack and shoe or decrease in the rate of such advance.

During the rotation of the work-carrier each arm thereof is controlledin such manner as to enable the shoe that is carried thereon to besupported firmly in proper position whilebeing acted upon by therespective buffing-surfaces. This control is effected by means of thefixed guide 0, Figs. 2, 3, 4, 11,

and 12. The body of the guide 0 is formed as 0 which is provided inconnection with each arm 7, travels around within the pathway of theguide. The guide is formed with fixed outer and inner walls or flanges 00 concentric with the work-carrier shaft h and extending around thelower portion of the guide and up at the front thereof. While the roll 0of an arm 7 is confined between the said fixed walls or flanges the armf with which such roll is connected and the jack and shoe carried by thesaid arm are caused to remain at a uniform distance from the center ofthe said shaft h. When the work-carrier stands at rest, one of the jacksis presented at the front of the machine, in osition to enable theworkman to remove a orm carrying a shoe which has been operated upon andapply a form carrying a shoe requiring to be buffed. At such time theroll 0 of the arm f supporting such jack occupies a position between theconcentric walls, and thus the jack is sustained while the operations ofremoving the one jack and shoe and applying. the other jack and shoe arebeing performed. In order to rovide for quick inward movementv of thejac and the shoe carried thereby as soon as by the regular advance ofthe work-carrier, the rear portion of the shank of the shoe has beensubmitted to the action of the first bufiingband 'i, and before thebreast of the heel has encountered the said buffing-band a hingedcontinuation 0 of the inner wall or flange 0 is employed. The saidhinged continuation is constituted by a curved piece or member (shown inplace in Figs. 11 and 12 of Sheet 3 and detached in Figs. 13 and 14 ofsaid sheet) that is mounted upon the fixed plate 0' by means of a pivot0 Fig. 11, with which is engaged the end of the said piece or memberthat is next adjacent the proximate end of the inner wall or flange 0Normally the piece or member 0 is held in its outer or working positionby means of a hooked latch 0 which engages therewith, the hook of thelatchbeing held in engagement with the piece or member 0 through theaction of an expanding spiral spring 0", Fig. 12, that is comressedbetween the latch and an adjacent ed strip 0 u onthe plate 0. As the;shoe travels under t e buffing-band i and the sole and shank are actedupon thereby the roll 0 passes along the inner wall 0 and froni the uper end thereof onto the piece or member 0, W 'ch at that time is heldin\place by latch 0 so as to sup ort the arm f and jack. On thearrivalof t e forward end or breast of the heel in close proximity tothe buffing-band the latch 0 is tripped, so as to release the piece ormember 0 thereby rendering the part 0 free to give way under thepressure of the roll 0 thereagainst. This permits the arm f to swingsuddenly inward toward the: center of the w0rkcarrier.' In order toenable the tripping of the latch o to be effected at the pro er-time,the said latch is furnished with a tai piece extending through anopening 0 in the fixed plate into the path ofa cam projection 0 Fig. 2of Sheet 2 and Figs. 23 and 25 of Sheet 7, which is carried by asuitable support upon and rotating with the work-carrier shaft h. Forconvenience the fixed member n of the adjustable controllingcam for thecarrier-frames of the buflingbands is utilized as such'support. In orderto render the action of the cam-piece 0 upon the tail of the latch 0easy, the said tail is furnished with an antifrictlon-roll to receivethe ressure ofthe cam-piece. The bufiingban '2', and breast of the heelof the shoe having been caused to clear each other by the movement ofthe jack and shoe inward toward the center of the work-carrier and thesimulwithlatch 0 'sented properly to the action of the b elevatingcam-piece 0, Figs. 1 1, 15, and 16 of Sheet 3, by which the arm f ismoved outward again to its previous position, thereby placing the shoein position to have the sole and shank thereof acted upon by the secondbuffing-band in passing the latter. From the fixed elevating cam-piece 0the roll 0 passes onto a second movable piece or member 0 resembling themovable and provided with a late 0, corresponding This latch 0 holds themovable piece or member 0 while the sole and shank of the shoe are beingoperated upon by the second bufling-band j and then in turn is trippedby the cam projection 0 to release the movable piece or member 0 so asto allow arm to again swing inward, as soon 1piece or member 0, r

as the rear portion of the shank of the shoe has been acted upon by thebuffingband j to cause the front end or breast of the heel of the shoeto clear the second bufiingband 7'. A second fixed elevating campiece 0moves the arm f outward again to place the shoein position to have thewear-surface of its heel operated upon by the heel-buifing surfaces lcZ. After passing from the fixed campiece 0 the roll 0 enters between theinner wall or flange 0 and outer wall or flange 0 and is confined so asto support the arm f at a uniform distance from the center of theworkcarrier as the shoe is carried past the heelbuffing surfaces andacted upon thereby.

Shoes of different thickness in the fore parts thereof require'radialadjustment of the jack upon the work-carrier to be effected in orderthat the bottoms of the soles, shanks, and heels of such shoes whenmounted upon the jack may be located at a redetermined distance fromthe'center, an thus be v .n surfaces. In order to provide for thisadjusi ment, we provide means for effecting a radial adjustment of arm fupon the work-carrier;

0, Figs. 3, 4, 6, and 7, alongside the arm The arm 0 is controlled bythe guide 0 through the engagement of the roll 0 with such guide. It issupported by one end thereof upon the pivot f carried by the bod portion9, upon which the arm f is mounte The arms f and 0 are clamped togetherby 'means of a screw 0,Figs. 3, 4, and 5, the

stem of which passes through a slot 0" in the arm f and enters athreaded hole that is tapped in the arm 0". The slot 0 is concentricwith the pivot f and enables the arm f to be adjusted radially withrelation to arm 0". On tightening up this screw 0 the arms f and 0 aresecured together, with the arm f in the position relative to the arm 0into which it has been adjusted.

a In order to enable the jack and the shoe To this end we-mount the roll0 upon an arm thereon to be adjusted in the direction of the lengththereof upon the work-carrier, so as to locate the breast of the heel ofsuch shoe at the proper point to enable the shank of such shoe to bebuffed close to the said breast without leaving a portion of the shankunbuffed and without engagement of the front end or breast of the heelwith the buffingband, the jack is mounted upon the arm with capacity foradjustment toward and from the pivot f. Thus the jack e is attached to ablock f (Shown separately in Figs. 9 and of Sheet 4.) The said block isfitted between upper and lower guideways f 3 x 5 f 3 upon the arm f,extendin lengthwiseof the latter. The block is hel to the arm by meansof a screwf, Fig. 7, the stem of which passes transversely through aslot f in the arm f, extending lengthwise of the latter, and enters athreaded hole f Figs. 9 and 1'O,,tha=t is tapped in the block. The slotf permits adjustment of the block and .'ack longitudinally of the arm tobe effected by sliding the block alon the said guideways f 3 To enablethe adjustment to be accomplished conveniently and with certainty, anadjustingscrew f is provided. This adjusting-screw is formed withcollars receiving between them fixed lugs orprojections extending fromthe outer end of arm f, as shown, whereby the adjusti-ng-screw is heldfrom longitudinal movement, while the threaded stem of the same enters athreaded hole f 'Fi s. 9 and 10, that is tapped into one end 0 the tionsin the position of the breast of the heel of; a shoe with respect to thelength of the s oe.

For the purpose of enabling the jack to be adjusted, so that thelongitudinal curve of the outer surface of the sole of a shoe carried bya form upon said jack shall be as nearly as possible concentric with theaxis of rotation of the work-carrier, the jack is, pivotally mounted at6 upon the block f and is provided with means to enable it to beadjusted around the pivot. The closer the approach to concentricity themore nearly uniform will be the tension of the buffing-band whenoperating upon the different portions of thelength of the sole andshank. In order to hold the jack secured in the desired position ofanguar adjustment relative to its pivot, it is provided with aclamping-screw e the stem of which passes through a segmental slot e,Fig. 8, in the jack, that is'concentric with the pivot ate and enters athreaded hole f Figs. 9 and 10, which is tapped in block f On tighteningup said clamping-screw the body of the jackbecomes pinched between theblock f 2 and an enlargement or collar upon the screw and is therebyheld. Should the angular adjustment of the jack relative to pivot edisplace the breast of the heel, a 65 compensating shift of block f 2may be effectblock. This adjustment provides for variaa worm-gear p,Figs. 1, 1*, and 2, which is mounted upon the shaft 7L of suchwork-carrier, a worm p, Figs. 1-and'2, in engagement with the saidworm-gear, a worm-shaft p mounted in bearings p upon the correspondingside frame 0 the machine and extending 1n the direction from front torear "inthe machine, a miter-gear fixed upon the rear end of the'wo'rm-shafit, (see also Fig. 33,) and a miter-gear p fast u on thedriving-shaft b. We provide clutc' devices by means of which to controlthe "actuation of the work-carrier through the connections described.The clutch in the present instance serves to enable the worm-gear jo,which is loose upon the work-carrier shaft h, to {be connected with thesaid sha'ft, so that the work-carrier and worm-gear shall rotate inunison or to be disconnected from "the shaft h, so as -to discontinuethe transmission of driving power to the work-'cairier. The characterand mode of operation of the clutch devices may be varied in practice.

The said clutch devices may be arranged to operate the work-carriercontinuously after t e clutch has been closed b the workman until theclutch isunshippe again by him. Preferably, however, they are of thewell known start-and-stop type and operate when brought into action tocommunicate "onehalf rotation to the work carr'ier and thenautomatically disconnect the driving power from the latter. stop devicesin the present instance. Devices of this character being well known andin common use in the arts, we have simply indicated in Figs. 1, 1, and 2the relations of the clutch to the worm-gear and theclutchactuatindevices and have "omitted minor details 0 construction. To enable theact'uation of each work-carrier to be controlled manually, we provide atreadle p Fig. '1, which is pivoted at its rear end, as at p, to thestand a. To the said treadle is connected the lower extremity of a rodor link p", having the upper extremity thereof connected to a lever p,which is pivoted at 11 to a small stand p, projectingforward from thecorresponding side frame of the machine and having its forward extremityconnected by a rod or link p" to the actuating-arm p of the clutch, thesaid actuatin -arin being pivoted upon a small stand Fig. 1, that isalso We have shown 'start a'ndcarried by the said side frame.

Having reference now' to the figures mentioned, thebuffingband i is mounted upon opposite guide and tension pulleys i i andan intermediaLtelylocated driver-pulley it The pulleys i 'i' are mountedpivotally upon the lower ends of arms i i whi ch are hung upon pivots 712" at the forward end of a carrier-frame t thelatter being mounted uponthe machineframe by means of journals i i at its rear end fitting thebearings 77 i, with which the machine-frame is provided. The pulley i isfast upon the forward end of a shaft i which latter is journaled inbearings 41", with .which the said carrier-frame is furnished.

For the purposeof driving the shaft i the latter is provided with aband-pulley i",

which is mounted on the rear end thereof and shank of a shoe the arms ii are acted upon by spring-pressure, tending to move the same and thepulleys i z" in opposite directions, and

thus extend the buffing-band with yielding force. Thus, as shown best inFig. 22, the forward end of the bulfing-band frame '5 is formed orprovided with sockets i. '5, re-

ceivifigplilngers i i which project partly from the said sockets andbear by their outer ends against the arms i i Between the inner ends ofthe said plungers and the inner ends of the said sockets are locatedexpanding spiral springs 1' 11 which act through the plungers upon thearms 11 t with a tendency to move the arms away from each other. Thecarrier-frame for the buffingband 7' is designated 7' Figs. 1, 17,and-33, it

being mounted by journals 7', Figs. 1, 17 and which in the upper portionof its circuit passes around the band-pulley 2' of the operatingshaftfor the buffing-band i and in the lower portion of its circuit passesaround the bandpulley j of the operating-shaft for the buffing-band 1'.For the purpose .of actuating the said driving-band i a secondary shaft11 is mounted in bearings i at the rear of the machine-frame, the saidshaft being driven from the driving-shaft b, as by means of a l band'5", Figs. 17 and 33, passing around driving-pulleys 2' and 2' on thesecondary shaft 11 and driving-shaft b, respectively. Upon the shaft 01are mounted a pair of pulleys i i' for each half orsection of themachine, Fig. 33, the two portions of the driving-band 11 passing overand partly around the said pulleys in going to and returning. from theband-pulleys 1. One of the said pulleys on shaft i as, for instance,that designated i is fast upon the shaft 4, and drives the" bandi byits'frictional contact with the latter. The other of thesaid pulleys, as11 is loose upon the said shaft and serves simply as an idler or guidepulley. Idler-pulleys i 71 beneath which the band 13 passes, are mountedupon a shaft 11 adjacent the point .of pivotal support of thecarrier-frame "L for the buffing-band i.

The buffin -,band-carrier frames i i are caused to tend toward the pathin which the shoe travels, so as to cause the buffing-bands to makecontact with the bottom of the shank and sole of the shoe bya yieldingforce suitably produced. In the present instance the said carrier-framesare mounted so that they ravitatc toward the said path, as indicated yFigs. 1, 2, and 17, the action of gravity being aided by the springs 'mm, which hold the actuating arms or levers m m, presently to bedescribed, in en agement with the cam by which the carrierames are movedoutward to retract the buffing-bands, so as to clear the heel of theshoe.

The means by which when the rearmost portion of the shank of a shoe hasbeen acted upon by one of the buffing-bands outward movement of thecarrier-frame for the said bufiin -band is occasioned in order towithdraw t e buffing-band from its operative position before it has beenencountered by the forward end or breast of the heel and by which thecarrier-frame is held outward until the toe portion of the sole of thenext succeeding shoe upon the work-carrier has been 7 tion and anadjustable portion.

presented by the'advance of the work-carrier in position to receive thebuffing-band is shown in Figs. 1, 2, and 17 to 30. It comprises the camlast referred to, such cam rotating in proper'timirig with respect tothe work-carrier and operatin connections between the said cam and t ecarrier-frame. The operating connections comprise the connecting-link mand actuating-lever m, Figs. 1, 2, and 17, the said connecting-linkhaving one extremity thereof joined to the said actuating-lever and thesaid actuating-lever having a roll or projection which makes contactwith the cam. The cam is fast upon the shaft 72. of the work-carrier. Itis double, as shown, to suit the number of jacks, one circumferentialhalf of the cam acting to move the buffing-bands "i successively outwardas one shoe passes the same and then the other half of the cam repeatingthe operation as the next shoe passes the said bufling-bands. In

order to provide for the differences which occur .1n the lengths ofshoes. the cam is made adjustable, each half thereof having a fixed por-Thus the cam is formed of a part or member n, (shown separately in Figs.25 and 26 of Sheet 7, which is relatively fixed with respect to theshaft and parts or members 11 n, each of which is adjustable withrelation to the said part or member n angularly about the shaft 71.. Thepurpose of the said adjustability is to enable the circumferentiallength of the oppositeactin portions of the cam to be varied to suitifferences in the length of the interval between the breast of the heelof one shoe upon the work-canrier and the toe portion of the sole of thenext succeeding shoe. The fixed part or member n of the cam is formedwith a hub niupon which the eye or boss n of each of the adjustableparts or members n n is fitted with capacity to turn around. the saidhub. Each of the said adjustable parts or members is held in the desiredposi tion by means of a clamping-screw n, Figs. 2, 23, and 24, the stemof whichpasses through a segmental slot a which is formed intheadjustable part or member n, into a threaded hole n", which is tappedin the fixed part or member n, the {said adjustable part or member beingclamped between the enlarged head of the screw and the said fixedmember.

'1 and 2 and in Figs. 31, 32, and 33 of Sheets 8,9, and 10. For the suppgrt of the roll or cylinder 1t 1s mounted to turnaround a fixed shaft k, which is carried by the outer extremitles ofarms k W, fast upon a supporting rock-shaft k which is fitted tohearings in upright portions of the machine-frame. The roll or cylinderZ similarly is mounted to turn around a fixed shaft 1, which is carriedby the outer extremities of arms 1 1 fast upon the supporting rock-shaftZ which is fixed in bearings in the said upright portions of the ma--chine-frame. The buffing roll or cylinder 7c is fitted to the exteriorof a sleeve is, the latter being fitted upon the fixed shaft is so as tobe free to turn thereon and being provided with a spline k, whichcompels the roll or cylinder and sleeve to turn together. In like mannerthe roll or cylinder Z isfitted upon a sleeve Z, having a spline Z andmounted upon shaft Z with freedom to turn thereon. For the purpose ofrotating each of the heel-buffing rolls or cylinders a bandpulle k Fig.31, is fixed upon the sleeve k of t e roll or. cylinder k, and a largeband-pulley k and a small band-pulley 7r", fast with each other, Figs.31 and 32, are sleeved upon the supporting rock-shaft k applied to theband-pulleys 70 Ye and a second driving-band k is applied to the smallband-pulley 7c and a larger band-pulley k, which is fast upon thedriving-shaft; b. Through the said bands and pulleys driving power istransmitted from the shaft 1) to the roll or cylinder k to rotate thelatter. The roll or cylinder Z is rotated in like manner from thedriving-shaft b through the agency of a band-pulley Z upon the sleeve Z,a large band-pulley Z and small band-pulley 1, fast A driving-band 7c isx with each other and sleeved upon the rockshaft 1 a band-pulley Z",fast upon-the driving-shaft b, a driving-band Z passing around andconnecting the pulleys Z Z and a driving-band l, passing around andconnecting the pulleys Z and. Z". In order to distribute the wear of thesurfaces of the rolls or cylinders k 1 throughout the length of the saidrolls or cylinders, provision is made for communicating an endwisemovement to each roll durin .the rotation thereof. Thus each of the rols k l is splined to its sleeve, as already explained, so as to cause itto rotate-m unison with the said sleeve, while permitting the roll tomove lengthwise along the same, and in order to occasion such lengthwiseInovement each roll or cylinder, is provided at one end thereof with areduced portion having a circumferential groove, as at ,may be, which ispivotally mounted upon a lug k or Z ,.projecting from one of the sup- Iey it (see also Fig. 2) is fast upon the shaft 7t porting-arms k or Z Apin or roll carried by the said traverse-lever works in the groove of. atraverse-cam k or Z fast upon a sleeve is or Z, that is mounted looselupon the corresponding rocker-shaft k or For the purpose-of rotating thecams is Z the respective sleeves 7c Z have'fast thereon bandulleys k Zrespectively, and a band-pulof the work-carrier, a driving-band kpassing around the three band-pulleys. h, In, and Z and servingto'transmit movement from the band-pulley h to the traverse-cams 1c 1when the wdrk-carrier is rotated.

For the purpose of enabling the swin frames carrying the rolls orcylinders 7c an Z to be operatively controlled an arm, as k or Z ismounted upon each of the rock-shafts The arm k is connected by-a rod 7c"with an arm k of the swing-frame carrying the roll or cylinder lc, so asto maintain the arm and swing-frame in fixed relations with respect toeach other, and a similar rod Z" connects the arm Z with an arm Z of theswingframe supporting the roll or cylinder Z. To cause the twoswing-frames to move in unison, the arms is Z are joined'together bymeans of a link Z Each of the arms k Z has connected therewith oneextremity of a con- 1 tracting spiral spring 1c or Z, the other exmoredelicate in its'action.

tremity of such spring bein connected to a fixed part of the machine-.aming and the said springs acting with a tendency to move or turn theswing-frames in the direction to move the rolls is Z toward thework-carrier. In practice one of the said springs may be omitted, ifdesired, although by the .use of two springs each of the same may bemade In order to guard against the possibility of undue movement ofpassin the swing-frames and rolls or cylinders 701 toward thework-carrier under the influence of the spring or springs, a stop in,Figs. 1 and 31, is mounted upon a fixed part of the machineframing inthe path of the arm 7c. To enable the angular relationship between thearms k v Z and the respective swing-frames to be varied, as for thepurpose of varying the degree of pressure of the rolls or cylinders andthe action of the said rolls or cylinders upon the wear-surface of thetop lift of a heel the rolls or cylinders, provision is made foradjusting the rods k Z in the direction of their length with respect tothe arms k l To this end the rods 7c" Ware connected with the arms k Iby passing them throu h swivels k Z Fig. 32, which are mounted upon thesaid arms, nuts 7c Z frames automatically are moved outward withrelation to the work-carrier against the tension of the springs is Z insetting thebufiing rolls or cylinders to suit the height of the heelwhich is next to be operated upon thereby and in gradually shifting thesame to conform to the inclination of the wear-surface of the top liftas the heel passes each of the rolls or cylinders.

For the purpose of enabling this movement to be communicated to theswingframe at the proper times the arm k is joined by a link t to an armt projecting rearwardly from a sleeve 1?, Fig. 32, the latter beingmounted upon a fixed shaft 11*, that is supported by the uprightportions of the machine-framing. When the sleeve is rocked upon itssupporting-shaft t movement is transmitted to. the

swing-frames through the connections described. For use in rocking thesleeve the r latter has loosely fitted upon the same at one side of thehub or collar of the arm t the hub or collar of an operating-arm u,Figs. 1, 2, 31, and 32. The said operating-arm projects forward and isjoined by a connection u to aradius-arm u which latter is pivoted at nto a small stand projecting from one of the upright portions of themachine-framing. To enable the radius-arm u to be operated at the a o 9proper times,the said arm carries a roll it, Flgs.-

2 and 32, for engagement with the settingcams of u and templet-cams 'u.a, respectively, Figs. 1, 2, and 31, which are mounted upon the disk u,fast upon the work-carrier shaft h. Movement communicated-to radiusarm uin consequence of the'action of the said cams against roll u istransmitted through the link to to the operating-arm it. At the time atwhich such action occurs the operating-arm u is locked or clutched tothe sleeve t clutching, the hub or collar of the operatingarm 11. isformed or provided with a conical flange or shell u, constituting onemember of a clutch, and a second clutch member u", having an exteriorcone to fit within the said flange or shell, is splined upon the sleevet so that it is free to move lengthwise upon the latter, while the saidclutch member 11, and sleeve are compelled to turn in umson.

cam-collar 0), Figs. 2 and 32,mounted loosely IIO In-order to effect thelooking or In one posimember it toward the left in Fig. 2, (the right inFig. 32,) with the exterior. of the said clutch member pressed tightlyagainst the interior of the flange or shell u The latter is backed up bythe hub or collar of arm t. Consequently through the engagement of thetwo clutch members the operating-arm u is clutched or locked to thesleeve t so that movement communicated to the operatingarm as a resultof the engagement of either a settingcam or a templetcam with the roll ais imparted to the said sleeve to be transmitted through arm t to theswing-frames carrying the buffing rolls or cylinders. In anotherposition of the cam-collar the pressure by which the clutch members arecaused to engage with each other is relaxed, and the sleeve and itsconnections are left free to be turned reversely under the influence ofthe tension of the springs It 1". The cam-collar is operated to cause itto assume the two positions aforesaid alternately by means of a forkedarm o projecting therefrom, Figs. 1 and 31, the slot of the said armbeing entered by one arm of a rocker w ,which is mounted pivotally at oupon one of the upright portions of the machine-framing. The long arm ofthe said rocker is joined by a connection '0 to a radius-arm 12, whichis pivoted upon the said upright portion of the machine-framing. A rollcarried by the radius-arm v bears against the periphery of a cam-diski), which is fast upon the work-carrier shaft it. Through the action ofthe raised portions of the periphery of the cam-disk v the clutch isheld closed normally, keeping the operating arm to in operativerelationswith the sleeve F; but by means of notches or depressions 12, 0which are formed in the periphery of the camdisk at diametricallyopposite points, the said clutch is allowed to open for a brief intervaltwice in each rotation of the work-carrier, thereby disconnecting theoperating arm and sleeve from each other.

The setting-cams u and templet-cams u correspond in form. Each thereofis formed with a groove,into the leading end of which the roll of,carried by the radius-arm a enters as the cam approaches such roll inthe turning movement of the camdisk u, and each thereof is formed withan ascending grade acting upon the said roll to move the latter outwardand upward in the resent instance, occasioning thereby outwar movementof the res ective heel-buffing rolls or cylinders k Z. n the presentinstance the setting and templet cams are disposed in groups upon thecam-disk 117, each of such groups comprising two templet-cams and asetting-cam. The first templet-cam of each group is timed to act as theheel of a shoe is presented to the o eration of the first bufling rollor cylinder and in consequence of gradually pressing outward the rollaforesaid it operates to occasion a gradual outward shift of the bufiingrolls or cylinders, thereby causing the roll or cylinder k to conform tothe outward inclination of the wear-surface of the top lift of the saidheel while the latter is being carried past the same. After the heel hasbeen carried by the rotation of the work-carrier beyond the bufiing rollor cylinder 1c the first templet-cam permits the swingframes to beturned by their springs k Z so as to shift the buffing rolls orcylinders is Z inward into their normal ositions again. As the breastend of the bee reaches the second buffing roll or cylinder Z the rollerenters the leading end of the second templet-eam u of the group, asshown by Fi s. 1 and 31, and the o eration by which the eel-buffingrolls or cy inders are gradually shifted outward to cause the secondroll or cylinder 1 to conform to the incline of the Wear-surface of theheel is repeated. The heel of this shoe having been carried past thesecond buffinglroll or cylinder Z, the" operationof setting t eheelbuifing devices in readiness for operating upon the heel of the nextsucceeding shoe is erformed prior to the arrival of the latter heel atthe first heel-buffing roll or cylinder k. To this end a setting-cam nand a gage or measuring device t are brought into operation during theinterval. The said gage or measuring device is constituted by a rollwhich is mounted upon an arm t,fast upon sleeve t and projecting forwardtherefrom. It may occupy a position at any convenient oint in themachine, enablin the wear-sur face of the top lift of the heel o a shoemounted upon the work-carrier to make contact with the same in advanceof the arrivalof the said heel at the first heel-buffing roll or cylin-(fer. In the resent machine the gage or measuring device is locatedintermediate the first and second buffing-bands-i and By the continuedrotation of the work-carrier the setting-cam a pertaining to the grouaforesaid, s caused to act upon the roll u",-1t being capable ofoccasioning, through theiconnectlons described, an outward movement ofthe operating-arm u and also of the heelbufling rolls or cylinderssimilar to that which is produced by the action of the templetcams u a.As the roll it travels within the groove of the setting-cam the heelwhich is next to be buffed passes into position to cooperate with the gae or measuring device (roll) t. Also one o the notches v of camdisk 12is presented to the roll that is mounted upon arm v. By the entrance ofthe latter roll into the said notch the rocker v is caused to turn thecam-collar 1) so as to unclutch arm a from sleeve t freeing the sleeve tand its connections to the control of springs k Z and permitting thesaid sleeve and connections to assume positions determined by thecontact of the gage twith the wear-surface of the top lift of the heel.In other words, the positions of the heel-buffing rolls or cylin-,

x the radius-arm a ders at this time will be determined by that whichthe gage t assumes when makin contact with the wear-surface of the topift of the heel about to be buffed. As ,the heel passes the gage-rolltits wear-surface presses the latter outward, the rolls or cylinders 76I being correspondingly moved throu h the connections of said age androlls or cy inders with the sleeve t this action progressingsimultaneously with the outward movement of the operating-arm u that isoccasioned by the action of the ascending grade of the setting-cam 11,upon the roll a, mounted upon The conjoint action ro gresses until theroll a arrives'at the big est point of the said ascending grade and thegageroll t reaches the rounded rear end of the heel, at which moment thecam-surface at the rear side of the notch 21 in the cam-disk 1)" acts toraise the arm '0", thus operating the rocker v to clutch the arm at tothe sleeve t again. Thereby the heel-buffing devices are I set to suitthe height of the heel which has just passed the gage-roll. By thesucceeding raised peripheral portion of the cam-disk v the said arm iscaused to remain locked in fixed relations to the sleeve 25 until afterthe heel has passed the two rolls 7c and Z. As it thus passes thesucceeding templetcams n w act successively to roduce the outward shiftof the rolls in Z as t e heel passes each roll or cylinder. It will beperceived that inasmuch as the templetcams and setting-cams correspondin their action upon roll w each of the said succeeding tem let-cams u uwill in turn transmit to the fieel-bufiing rolls or cylinders is I asthe heel passes it the same movement that Was communicated to the saidrolls or cylinders by the action of the said heel against the gage t.
